Is there a list of malicious IP addresses which have listed as intruders? I would like to add it to my personal firewall in order to prevent problems, thank you

There is a program called Peer Guardian (/http://www.methlabs.org/methlabs.htm)
That runs in the background to filter about 10,000 IP's. If you run a server it is a good program to have.

You can get spybot and it has a host file you can download.
